Featured Presentation:

Deep Dive into Blocking and Deadlock Troubleshooting

Dmitri Korotkevitch, Director, Database Services Chewy

SQL Server Concurrency Model is, perhaps, the most confusing and least understood part of SQL Server Internals. Blocking issues and deadlocks occur unexpectedly and negatively impact performance and user experience in the systems. Nevertheless, this model is well-structured and easy to understand when you analyze it from lock types and their lifetime and compatibility standpoint. This, two-part session will explain why blocking and deadlocks occur and how to troubleshoot them in your environments. First, it will provide the overview of SQL Server Concurrency Model and describe SQL Server locking behavior and root-causes of typical blocking issues. Next, the session will discuss how to capture and troubleshoot them using standard SQL Server tools, and how to simplify the analysis using Blocking Monitoring Framework developed by Dmitri.
